The King, Retuned and Refined

More than one and half years after its initial release, the most popular and praised Thieaudio Signature series IEM is ready to make a comeback! The Monarch has been completely redefined with driver overhauls and an enhanced tuning. The Monarch was a monumental milestone for both Thieaudio and the global audio community, hallmarking not only one of the first IEM’s to properly integrate the EST driver technology, but also firmly establishing Thieaudio’s place in the world of Hi-Fi audio. Our R&D team has been following up with the reviews and comments from the audiophile community to refine that which was already one of the most revered monitors of its class and present the ultimate form of the Monarch: Monarch Mark II. 

A New Engine to Set New Limits

Our goal for the Monarch MKII was to enhance its technical performance and introduce a more balanced tuning, while staying true to the original spirit of this monitor. We took this opportunity to update all of the internal drivers, swapping them out for their latest counterparts and rearranging their configurations to achieve an even more optimal performance.

The 10mm dynamic driver has been upgraded to a brand new composite diaphragm driver. With a tremendous increase in membrane tension and magnet strength, the new driver allows extreme responsiveness. And when engineered to specifically reproduce only the sub-bass frequencies, this dynamic driver becomes a subwoofer, producing even tighter and more impactful kick drum and bass line punches. Additionally, two dedicated subwoofer balanced armature drivers were paired with the dynamic driver, bringing about an immaculate coherency between the lows and the rest of the frequency spectrum.

Driver Configuration

The heart of the Monarch has always been its extremely precise and neutral mids that make it such a capable studio monitor. To emphasize this trait, we reconfigured the balanced armature drivers, reinforcing this core range with four mid-frequency drivers.

Doubling the midrange drivers from the original Monarch presented incredible advances in technical performance. Distortion was reduced, while the resolution, clarity, and articulation of the mid and treble sections were significantly enhanced. This single change was enough to make the Monarch MKII feel like a completely new beast compared to its predecessor, all the while still maintaining the characteristic studio-neutral midrange.

Latest Technology

The latest electrostatic drivers are incorporated into the Monarch MKII, and rearrangement of driver location has minimized unwanted tubing resonance and extended its high frequency rolloff compared to the original Monarch. This means that the treble range is more even and detailed, and our innovative incorporation of the EST drivers into the setup allows for a greater sense of sparkly, airy, and high-resolution atmosphere in your music. The Monarch MKII continues the Thieaudio legacy of being one of the few in-ear monitors in the world to properly utilize the EST technology.

Retuned for a Balanced Perfection

One of the controversial sound aspects of the original Monarch was its super defined and emphasized sub-bass. While some enjoyed the clean separation between the sub-bass and the low-mid frequencies, others voiced concern of the sheer quantity of sub-bass. To bring about a resolution, we have slightly decreased the volume of the sub-bass to more appropriate levels, while pushing the low-pass crossover from 150Hz to 200Hz. This change still maintains the clean and punchy subwoofer-like characteristic of the lows that doesn’t muddy the mids, but introduces an ever-slightly warm texture to fundamental low-frequency instruments such as the bass guitar.

The mid-frequencies between 200Hz and 1kHz are still kept at a ruler-flat neutral that makes the Monarch MKII an impeccable professional monitoring device. The mid-treble transition between 1 and 2kHz has been pushed back to 3kHz, which reduces any nasal or harsh vocal textures, while still emphasizing the bite and crispness of instruments. Every aspect of the tuning process has been scrutinized, being meticulously tested by ear and measurement equipment, and we are proud to present the perfect vision that is the Monarch MKII.

Premium Cable System

With our new release, we have also upgraded its previous EST cable. Beloved for both its feel and high resolution sonic properties, our EST cable has been one of our top selling products. We have improved the physical texture of the cable by using a soft braided paracord material.

The Monarch MKII's stock cable still maintains the ultra-pure silver plated 26AWG OCC copper litz wires, but the additional strand incorporation gives it a slightly meatier feel and a richer sound. Most significantly, this new stock cable features the proprietary "Smart Switch", a new modular plug design, allowing you to choose between 4.4mm balanced, 2.5mm balanced and 3.5mm unbalanced terminations, simply by swapping out the plug ends. This reduces the need for bulky adaptors, giving your setup a more complete look and feel. The 2-pin connectors on the stock cable are also updated to provide a more secure fit with your IEMs.

Great product and service

I had originally purchased this product back in August, but I ran into QC issues so I had to exchange it. So the product itself is a 5 star, but because of the issue, I was going to dock 1 or even 2 stars for having QC issues at this price. However, their service was also excellent. Their service rep was highly responsive and responded to all my inquiries within a business day, and I had sent several. The exchange process took over a month, but that is understandable as I am from the US. So great product, great service.

great IEM great service

I ordered the MKII after owning various other IEM’s looking for one that can do it all and yes this is the one that can do no wrong if you care about clarity and music sounding “correct”

My favorite

I have a few other IEM's, Fiio FH 7's, Ikko OH 10's and Dunu SA6's, and while I enjoy them all these are my favorites. I'm not very eloquent in describing why, all I can say is I have no regrets buying these. I mostly listen to rock music and take my dog for long walks 4 times a week and these shine in comfort (usually walk for about an hour and a half), sound (never hearing fatigue) and look fantastic.

Great iem

Not complains about the iem only the cable, for 90usd cable its should be flexible enough, also they forgot to put glue in the plastic protector which is disappointing, i had to use glue myself just to fix that.

Hello there.
You have been using the IEM and cable for months and you are now claiming that our manufacturer 'forgot to put glue'.
However, all our cables are properly soldered and tested with the IEMs during the Quality Control process.
Thank you for the feedback, nonetheless.

Worth the upgrade

I was worried that the upgrade from the Moondrop Blessing 2 Dusk to the Thieaudio Monarch Mk II would not be worth the price because of the law of diminishing returns. My fears have been proven wrong and I am very happy with this purchase. The sound of the Monarch Mk II is much better than the already outstanding Blessing 2. To those on the fence, if you like the sound of the Moondrop Blessing 2 Dusk, the Thieaudio Monarch Mk II is an upgrade you will not regret.

Best sounding IEM I've purchased

Granted I've not tried out too many, but comparing to the ones I do have (7Hz Timeless, Moondrop Blessing 2 & AKG N400NC), the Monarch MK II have far superior clarity of the sound being delivered through my dank lil Fiio BTR5

Of course it's also one IEM that costs significantly more than all the others I've purchased (with AKG's only being 50$ when I got it), I guess it'd make sense. However if you are looking for the best sound of the bunch I don't think you'd go wrong with Monarch MK II.

Potential End game?

After taking the plunge and buying the Mon MKII, I had high hopes. Maybe even too high some may say. But I’m happy to report that after a few months with them, I can confirm they’re fantastic.

I’m no reviewer so please take what I’m about to say with a grain of salt. A very large grain of salt.

Bass is handled well. The Mons have a scoop in the mid bass region, thus giving the Vocals a very natural playback. Some may consider the Mid bass lacking to some degree, but I don’t have this issue. With dance/electronic, rap, or R&B tracks where the mid bass is mastered to have extra punch, I find that it’s the perfect amount on the Monarchs. Sub bass is great, good rumble, not bass head level, but enough to hear and absolutely feel it. One thing that stands out with the monarch’s is that the Low end has texture. Something I never quite understood with my less expensive sets. The monarch has literal texture in the sound, especially with drum kicks. The quantity may not be earth shattering, but the quality Of the low end is fantastic.

Onto the mids, I mean What can I say? I think these have the most natural sounding mid range I’ve ever heard. They are clear and crisp with amazing timbre. There are some songs where the vocalist literally sounds like they are in the same room with me. I mean, it’s truly amazing.

The treble is handled well too. This set is more neutral with a bass boost than anything, so treble is not too much, but it has enough sparkle to shine micro and macro details. One thing to note however, and this maybe down to ear anatomy but for me, 2khz comes off as somewhat harsh in some tracks, particularly with female vocalists. It may have something to do with that EST as some people have noted that EST timbre can come across as harsh in some cases. Other wise, the monarch’s have nice air up top with beautifully rendered cymbal strikes and upper harmonics on say, electric guitars.

Technicalities are amazing as you’d expect. Resolution is TOTL. Imaging is good, not the best I’ve heard actually but very good nonetheless. Stage is very wide and particularly tall, actually. Another detail I’ve yet to experience as well with my less expensive sets.

That does it! Sorry for such a ridiculously long write up!

Awesome mids, best vocals I heard so far, sub-bass is good but the mid-bass lacks punch / slam, otherwise it would be perfect for me. Overall a very satisfactory purchase as long as you don't mind the bass too much.
